SH Oxidation Stimulates Calcium Release Channels (Ryanodine Receptors) From Excitable Cells
The effects of redox reagents on the activity of the intracellular calcium release channels (ryanodine receptors) of skeletal and cardiac muscle, or brain cortex neurons, was examined. In lipid bilayer experiments, oxidizing agents (2,2'-dithiodipyridine

Role of calcium-activated potassium channels in the heart
Ability of intracellular calcium to open K+-selective channels in an excitable membrane and to hasten repolarization of an action potential or inhibit firing is a fundamental principle of biology first recognized in the mid-1970s. There are several types

T-type calcium channels functionally interact with spectrin (α/β) and ankyrin B
This study describes the functional interaction between the Cav3.1 and Cav3.2 T-type calcium channels and cytoskeletal spectrin (α/β) and ankyrin B proteins.

Quantitative aspects of L-type calcium currents [PDF]
Calcium currents in neurons and muscle cells have been classified as being one of 5 types of which four, L, N, P/Q and R were said to be high threshold and one, T, was designated low threshold. This review focuses on quantitative aspects of L-type currents.

Calcium Channel Blockers and Hypertension
Effective treatment of high blood pressure (BP) represents a key strategy for reducing the burden of hypertension-related cardiovascular and renal diseases. In spite of these well-established concepts, hypertension remains poorly controlled worldwide.

Calcium-permeable ion channels in control of autophagy and cancer
Autophagy, or cellular self-eating, is a tightly regulated cellular pathway the main purpose of which is lysosomal degradation and subsequent recycling of cytoplasmic material to maintain normal cellular homeostasis.

Thanks to a protein that helps fruit flies remain airborne, researchers have deciphered a key step in synapse maturation. [Fouquet et al.][1] show that the protein forms part of a synaptic structure that clusters the calcium channels necessary for neurotransmitter release.

Background Familial amyloidotic polyneuropathy (FAP) is a peripheral neuropathy caused by the extracellular accumulation and deposition of insoluble transthyretin (TTR) aggregates. However the molecular mechanism that underlies TTR toxicity in peripheral
